In the Foundations Edition – and in the larger editions – the 40 major headings are chapters, grouped under the eight parts (Part A to Part H). The chapters themselves are subdivided.

The 40 chapter headings below are also links. Click any chapter heading to see the main headings within them (further down the page). From there, click the “^” symbol that appears in the bottom right corner of the screen to return to the top of this page.
